Abstract
Antenna selection is performed in a multicarrier communication system based on antenna scores. In at least one embodiment, an antenna score is calculated for an antenna by determining grades for individual carriers associated with the antenna based on corresponding signal magnitude related parameters and then combining the grades in a predetermined fashion.
Claims23
A method for use in a multicarrier communication system, comprising:
- determining signal magnitude related parameters for carriers of a multicarrier signal received by a first antenna within a first estimator;
- assigning grades to said carriers of said multicarrier signal received by said first antenna based on said signal magnitude related parameters within a second estimator;
- calculating a total score for said first antenna using said grades within a combiner;
- and
- selecting an antenna to use as a receive antenna, from a group of antennas that includes said first antenna, using said total score of said first antenna within an antenna controller.
An apparatus for use in a multicarrier communication system, comprising:
- a first estimator to estimate signal magnitude related parameters for carriers of a multicarrier signal received by a first antenna;
- a second estimator to estimate grades for said carriers of said multicarrier signal received by said first antenna using said estimated signal magnitude related parameters;
- a combiner to determine a total score for said first antenna by combining grades of carriers of said multicarrier signal received by said first antenna;
- and
- an antenna controller to select an antenna, from a group of antennas that includes said first antenna, for use in communicating with a remote entity based on total scores of antennas in said group of antennas.
An article comprising a computer readable storage medium having instructions stored thereon that, when executed by a computing platform, result in:
